Capsize (Ex)

An old or older brine dragon can attempt to capsize a boat or ship by ramming it as a charge attack and making a CMB check. The DC of this check is 25 or the result of the boat captain’s Profession
(sailor) check, whichever is higher. For each size category larger the
ship is than the brine dragon’s size, the dragon takes a cumulative –10
penalty on the check.

Although not inherently evil, brine dragons
have little patience for kindness and philanthropy. As they age, they
grow more and more opinionated and obsessed with power—by adult age, a
brine dragon counts itself a failure if it doesn’t rule over a
collection of “lesser beings” such as humans, merfolk, locathah, or even
sahuagin.
